Krysař (1964)

Set in a wintry, haunting Prague, the mysterious Piper arrives at New Year’s Eve in a red car and meets Agnes and Kristian, who are struggling with social rejection and a pending marriage. Using his magical flute, he purges the city of rats—and later, corrupted townspeople—demanding a personal sacrifice in return for love and redemption.
